这句话究竟在说什么
这句话有双重含义。第一层:分散投资可以降低风险——即使你判断错了10%,全仓押注一只股票可能损失很大,但分散到20只股票,单只股票的失误影响就小得多。第二层更深:邓普顿暗示知道自己在做什么的投资者不需要太多分散——他们更应该集中投资自己最有把握的机会。对大多数人来说,分散是保护伞;但对认知足够深的人来说,过度分散反而稀释了阿尔法。
给普通投资者的可执行清单
一个真实故事 / 场景化情节
邓普顿自己的投资组合虽然持仓分散,但有一个明确的主题:全球低价股。他从不随机分散,而是在最大悲观时刻的各个市场中寻找最便宜的优质资产。这种有逻辑的分散比无脑持有100只股票更有效。
这句话在该大师思想体系里的位置
哈里·马科维茨:分散的唯一免费午餐:降低风险而不牺牲回报。
看不懂的商业模式,再热闹我也不碰。
No matter how hyped, I won't touch a business model I don't understand.
交易的艺术在于知道什么时候加仓,什么时候减仓。
The art of trading is knowing when to add to positions and when to reduce them.
对错并不重要,重要的是:对的时候赚了多少,错的时候亏了多少。
It's not whether you're right or wrong that's important, but how much money you make when you're right and how much you lose when you're wrong.
在商业世界里,我最惊讶的发现,是一种我称之为'机构惯性'的超级力量——它驱使管理层去模仿同行的行为,不管多么愚蠢。在抗拒机构惯性时,我的失败率比在收购好公司时还高。
My most surprising discovery: the overwhelming importance in business of an unseen force that we might call 'the institutional imperative.' In business, the institutional imperative drives managers to mindlessly imitate the behavior of their peers, no matter how foolish it may be. I have been more wrong about resisting the institutional imperative than I have been about buying good businesses.
